Abstract (en)
[origin: WO2013079372A1] For an electric auxiliary drive (1) for a bicycle, a planetary gearset (11) is arranged completely radially within a rotor (19) of an electric motor (10). The planetary gearset (11), the electric motor (10), and a pedal crankshaft (9) for driving a drive pinion (13) are arranged in a common housing (14). The electric auxiliary drive (1) is thus especially compact and can be produced economically.
